Command Line for the Web
flood6 writes "SearchEngineWatch offers a look at a new method of interacting with the Internet, YubNub. This 'social command line for the web' lets users create commands that interact with websites. Currently, most of the commands apply to search, but new commands could work with any site that accepts variables passed with HTML's GET command. For example, iap moon would search the Internet Archive for all media related to 'moon'."
John Gruber wrote a great essay on this called "The Location Field is the New Command Line". As he put it, "Web apps are just so damned easy to use ... It's all about the fact that you just type the URL and there's your email."
In FF, you can have bookmarks like this: http://livejournal.com/~%25s/ Give it a keyword (say, 'lj'), type in the URL line: lj someusername and someusername's livejournal opens. This is the simplest example. I have several more sophisticated; this mostly obviates the FF search box. And all this with a *very* simple syntax that only allows substitution of one string. Imagine something a bit more powerful in that place.
Computers make very fast, very accurate mistakes
The K desktop environment has things called "KIOslaves" which recognize certain pseudo-protocols on the Konqueror location bar (and other places).
Internet examples include "deb:" for Debian package searches, "rf:" for rpmfind, "gg:" for Google, "ggl:" for Google-I-feel-lucky, and "rfc:" for getting RFC text from the IETF website, and "wp:" for Wikipedia. There are lots of these.
Non-internet examples include "man:" for viewing man pages, and "info:" for viewing those otherwise horrible GNU info pages.
